Michael Hope bb9d516787 spi: sam0: fix CS and back-to-back transfers. ... Fixes #6577. Wait for all ongoing transmits to complete before de-asserting CS. When doing a tx then rx, wait for the previous tx to complete before flushing the rx buffer. Tested on the Arduino Zero against a Olimex MOD-NRF24L module.
